Thunderbird Support Forum

Hello, Everything was working well until Thunderbird updated to version 115. Now I get the "Login to server failed notice. I believe I have tried everything. I read all the help topics on the Thunderbird site, scoured google and youtube, and tried everything short of just moving to Outlook or something else. I even tried to revert back to an earlier version v102 but got the same failed notice. My Thunderbird program is stored on my Windows PC. I don't use an email client like gmail or outlook. Any help would be much appreciated. I'm running 3 email accounts and if I can't get this to work I'll probably have to switch all the email accounts. Thanks very much for your help.

Hi, I am looking for some help. I am using Windows 10, Comcast internet, and a VPN. I get error message when my VPN is on saying that my IP Address has bee blacklisted and I can not send or receive emails using Thunderbird. I also get an error within Thunderbird. My VPN Service says its either Comcast or Thunderbird. Been working with Comcast on the issue. Could it be a Thunderbird issue? My VPN Service says to reinstall Thunderbird but no guaranties that will help. Please let me know if there are any solutions I can try. Otherwise I may need to pay more for a dedicated IP Address. Thanks Marc

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

Thunderbird will not forward inline. I have the settings set to inline, and I have tried "Forward As" and selecting inline, but it will not forward inline, it always forwards as an attachment.

I only just noticed this today. I forwarded a message 10 hours ago and it worked fine, but no it will not.

Somehow my Thunderbird email password was changed and I didn't do it. How do I reset my password? Email [edited] @sbcglobal.net when or if you have an answer. Thanks.

I have established a group in Thunderbird. I want to send a group email to all the individuals in my group. I believe that in the past I could click on the group name in the address book and have all the emails within the group come up in the To line of the email. Now I have to click on the group and then on each individual, which sends their email to the To line, but then when I click on the second person, the email is sent to the individual in the To line of a new email. How can I choose at one time all the emails of individuals in the group?

I very very recently upgraded to Windows 11, but even though I have Firefox and Thunderbird running with no problem, when I click on an email address on a website, instead of going to Thunderbird, I get some Windows email app that I never saw when just a month ago when I was still using windows 10 clicking on an email address would bring me right to Thunderbird. How can I get Windows 11 to use Thunderbird and only Thunderbird. I am not a techie, so if you know a solution, please be as clear as possible. Thank you.

Hi. I have tried to set up my gmail email addresses in Thunderbird without success. When I reach the end of the process I get a window asking me to log into gmail but when I try to do that I get an error message. I have tried some of the fixes. Not entering my password, turning off 2 factor authentication, manual set up, but I still get the error message. Any help would be much appreciated. Thanks.

After installing version 78.4.0 (and continuing into 78.4.1), I have an issue with many of the folders in my Local Folders account. When I click on an affected Local Folder folder, it is not highlighted and no messages appear. Messages will appear if I scroll the mouse pointer over the message pane. I can then also read the messages, etc. If I move to another Local Folders folder, messages may appear or they may not (always the same folders) until I move the mouse pointer as described above. Note that the folder name is also not highlighted after clicking it. Sometimes the entire folder/account column on the left side of the screen is blank until I scroll the mouse pointer over that column. Very annoying! Any ideas? FYI - I have tried "repairing" the folders in question. That does cause the messages to appear but as soon as the folder loses focus, the problem reappears - meaning the messages disappear and do not reappear until I either scroll the mouse pointer over the message pane or re-repair the folder.

TBird version: 91.4.1 OS: Linux Mint Debian Edition (Debbie) / Cinnamon 5.0.7

Settings: Account Settings > Copies & Folders > Mesage Archives

Current setting is "Keep messsage archives in: Other [set to 'Archive' folder on IMAP mail server] - see settings-1.png Archive options = A single folder - see settings -2.png

Issue: when I archive from my inbox, the mails go into Yearly folder; I want the emails to go into a single folder.

I have tried to reset the configuration multiple times and restarted Thunderbird multiple times, issue still remains. Your assistance is appreciated. Let me know if you need additional information. Thanks!

I have two gmail accounts in Thunderbird. One will send and receive perfectly. The other account receives but will not send emails and keeps asking for a password when doing so. Both use the same SMTP settings of course. This happens if the account is setup IMAP or POP3. The password is valid as the account will login online though any browser and also with windows 11 email app. I have removed and re-inslalled the rogue account several times but to no avail. Even copying the password from the browser password cache and pasting into Thunderbird does not work. Any ideas?

How can I ... INSERT TEXT FILE CONTENTS INTO Thunderbird COMPOSER ?

WHY? Because I have pieces of reusable ("boilerplate") text that I want to include in different messages.

recently and without other changes that I am aware of my thunderbird pull down menus do not populate with text, or sporadically do so after delay of 15 - 30 seconds.

Does compacting affect the use and/or availability of disc space on a digital harddrive differently than it does on a mechanical harddrive? I have heard that processes such as defrag etc are not advisable for digital harddrives.

Thanks Howard Dahlberg

Google has announced that after May 30, 2022 third-party apps that log into google with account name and password (which I assume includes Thunderbird) will no longer be able to do so, as they will enable 2-step verification. I currently and for years have used Thunderbird to pick up my mail from 5 accounts, 3 of which are gmail accounts. Will I be able to continue using Thunderbird after May 30, 2022? I have been unsuccessful getting any helpful information from google itself. They don't have a list of "trusted" third party apps that will continue to work with them. Anything people know about this will be helpful to me and appreciated. Thanks.

In another question I received an answer to how to revert from beta to current version.

I realized I had another question somewhat related. When a problem occurs in beta, I know crash reports go in. Or are they going somewhere else?

I also know a report can be filed on bugzilla. I’ve done that and Felt like a spectator while everybody else fixed the problem.

Ought a person using beta not use this venue for such things?

Aggravations are fairly short lived with beta, I don’t mind if I am being helpful.

If I misunderstand and beta version is for “bug busters then I’m in wrong place.

And I need to revert.

Hi, In the new version of Thunderbird, the folder pane, despite having been set as directed, is invisible until I pass my cursor over it, and so is all the mail in the inbox invisible unless I swipe over it. Once I have written an email, both lists revert to this invisible appearance again. This is quite irritating. I would like to see the lists constantly as normal without having to continually swipe over them to make them appear.

Is there some way to stop this from happening?

Thank you

I have spent the last two days trying to re-establish receiving/sending emails on my Apple MacBook Pro using Thunderbird without success. This problem developed suddenly about 3 or 4 days ago and only affects the MacBook, not any other device (I have an iMac and two iPads). I have gone through the instructions in Thunderbird's support pages and those in Mozilla with no success.

How do I fix this please? Would the easiest way be to simply delete the account xxxxxxx.gmail.com from Thunderbird on my MacBook and re-instate it by adding it back in?

All the setting for IMAP and SMTP are correct and the username/password is identical on all my devices.
